Connected to the Grobo- No LED lights - [Resolved]

@Chris @Stephen
I hopped on the app and was prompted with “you’re not connected” message.

When trying to pair my device to grobos servers it fails I’m prompted to powercycle the grobo allowing 30 seconds to pass and try again.

I notice there are no LED light on the front. I check out What do the User LED colours mean? – Grobo Help Center
No mention of “no LED”

Try to connect again via the app. Suggests powercycling once more. Waited a little longer this time. Still no LED outside light :bulb:

Lights inside the unit work. Air stone is producing bubbles. WiFi shows the Grobo and allows pairing of device. (Holding down the button in the back for several seconds shows the grobo-xxxx). Roll through the password, success.

Finally allows me to see the grobo through the app as “online” I am able to engage the glass through the app, but still no LED?

Has anyone else encountered this? It appears everything else is functioning. An email was sent to support


Never seen this one before, but I’ll bet if that led is a plug in on a circuit board, it either wasn’t plugged in at all or wasn’t done properly. I may be wrong, but that’s my best guess :+1::v:


Thanks for the reply. The LED was working day 1 and 2. I entered day 3 an hour ago and created a journal entry

Disconnect happens sometime in this time period 4-5pm CST. No power outages or flickers. Grobo is secured to surge protector

I have since created a new journal entry as well to test more throughly if I was truly connected

Would a factory reset help any? I can’t access the factory reset instructions? :man_shrugging:

Dunno, I’d send a ticket, but I think you did that. You could take the top off and see for yourself. @Azuri could possibly help you in this regards, as I remember him saying he took his off. It might have been another person, but pretty sure it was him

Probably best to wait for support to get back to me. Not a big deal if it waits until Monday. From what I can tell, everything is working fine. Inside Lights, connected to app, can use the app and grobo button to engage lights and door, airstone functioning.

Pretty sure I have a refill or dump and fill coming up this weekend. Not totally sure when that happens (day4-7 of germ - current is day 3), so that should be interesting. I’ll post an update if something goes awry.

Appreciate the advice :+1:

Does anyone know how I’ll be notified of the dump/fill? Does it come in email? App notification? Inside lights change?

Thanks in advance

I had the same issue day two with wifi disconnect and I did the same thing you did. Have you tried to manually lock and unlock your unit or hold the back button down again until t turns green because that’s when mine came back on.

Thanks for the tip, but yes, I’ve done everything short of fill and empty.

I can lock and unlock the door using the button and using the app.

Hey guys,

Yes, I removed the wood top and followed the lead from the light to the circuit board. It just unplugs. I’ve unplugged mine as the pulsing blue light can be seen inside the grow chamber. I personally think this stresses a plant that should be in darkness.


I Just re-read your concern, yeah take off the wood top and you will see a little plastic connector I bet it’s not plugged into the circuit board.

Would it have come loose? It worked day 1 and 2

No earthquakes and it hasn’t moved


Hmm hard to say it might have only been partially connected and maybe just not pushed in enough?


Fair enough, could’ve shifted in transit.

Do you remember the steps you took to disassemble or how many screws You needed to remove?

I could just open the bottom panel on the back and check for loose connections?

I may have a different version that you as well. The inside of my door has two screws on top and 3 hold the door

The wood top has two screws at the top in the front accessible when door is open and two screws around the same location in the back at top. None of the side screws need to come off. Once’s those four screws are out the wood lifts straight up.


So do I really need the outside LED? You mentioned you unplugged yours altogether.

Does the app notify you that you need a drain and or fill?

Trying going into the web based app click your light settings option then change the light setting… save it then go back and put it to light setting you want and the lights might turn back on and run normally … this happens to me all the time. Only other thing is your exhaust that cools the led is not working and that alert the software to not turn on the led In efforts to not overheat it


Personally having a new machine the lights have been imperative to figuring things out quickly.

The LED light on the front of your Grobo shows the different states that your Grobo One is in. Below you can see what each colour and pattern means for your Grobo:

pink.png Pulsing Pink: Grobo One is booting up, your unit will be ready to start growing soon!

green.png Solid Green: Grobo One is ready to connect to the internet. Follow instructions on how to connect to WiFi.

light_blue.png Pulsing Light Blue: Grobo One is connected to the internet and running as it should be!

light_blue.png Fast Blinking Light Blue: Grobo One has lost connection to the internet. It should reconnect on it’s own in a few minutes. If not, unplug and plug the unit back in to get connected again!

yellow.png Pulsing Orange: Grobo One is growing your plant but it’s lost the internet connection. You’ll only be able to use the Grobo app when your Grobo One reconnects to WiFi.
Otherwise these all look pretty good.

blue.png Pulsing Blue: Grobo One is in a special mode Ex. Filling, draining, door unlocked

red.png Solid Red: Grobo One has a critical error - if this occurs for longer than a few minutes, try resetting your Grobo.

If that does not work, please contact our support team:

purple.png Blinking Purple: Grobo One is flashing new firmware. Firmware is like the brain of your Grobo. We will periodically push updates to your Grobo to better your growing experience, so you don’t need to worry about this one!


Never thought of changing the light settings and saving - fix

Tried it and it didn’t work for me. The settings change, saved a quick blackout inside the grobo. Still no Outside light LED

Thanks, was worth a try

Wait which might we talking the actual grow light or the led that flashes ?

The Outside LED that was flashing all the time

If the app or email notifies me of updates or drains and fills then I don’t need the LED

How do the fill and drains notifications happen?

The light has zero impact on anything. It simply an indicator of wifi connectivity. Mine has been unplugged for the last two grows.

Think of it like the little light on a laptop or PC that shows hard drive activity. If you unplug the light function in the background is still happening but just no indicator light.

Bottom line, the light if pulsing blue means connected to your wifi network. I know my unit has no issues with this so I unplugged the “dummy” light (no disrespect meant) and all app functions, notifications and lastly wifi all work I just don’t have a dummy light.

I have purposely unplugged mine. I don’t not like the pulsing light in the grow chamber when it should be in total darkness. Maybe I’m too OCD but I found some bananas on my first grow so I don’t know what the source of stress was so I’m making sure it isn’t the pulsing blue light leak as I call it.
